4043 aluminium alloy[1][2][3] is a wrought aluminium alloy with good corrosion resistance typically used as filler material[4][5] for welding of aluminium parts. It contains high amounts of silicon (between 4.5 and 6%) and trace amounts of other metals.[6] It is grey in appearance and is sold as either welding wire or welding rod for TIG/MIG processes.

Chemical composition

Aluminium is the remainder.[4][7][8][9][10]
